Answer:

No this is not a function since 2 of the domain values have the same range.

Step-by-step explanation:

Well in simpler terms, if one or more range values (right side) have more then 1 arrow pointing to them, its automatically not a function. If each one has one arrow pointing towards them, its a function.

Answer:

(23, -1)

Step-by-step explanation:

I think you meant 2p + 39q = 7 , & 3p + 59q = 10

You would do C first, because that will get rid of the P's.

---> -6p - 117q = -21

---> 6P + 118q = 20

Now we get q=-1

If we plug it into the first equation, we get 2p + 39(-1) = 7

Therefpre, 2p - 39 = 7. This means that 2p = 46.

Therefore, p = 23

(23, -1)

Answer:

1. The facts are;

[tex]\overline x _1[/tex] = 95 days

s₁ = 32 days

n₁ = 18 SUV's

[tex]\overline x _2[/tex] = 48 days

n₂ = 38 small cars

s₂  = 24 days

The confidence level = 95%

The confidence interval is (29.55,  64.45)

Step-by-step explanation:

The facts of the problem are;

The number of SUV's he sold, n₁ = 18 SUV's

The average number it took to sell the 18 SUV's, [tex]\overline x _1[/tex] = 95 days

The standard deviation of the time it took to sell the 18 SUV's, s₁ = 32 days

The number of small cars he sold, n₂ = 38 small cars

The average number it took to sell the 38 small cars, [tex]\overline x _2[/tex] = 48 days

The standard deviation of the time it took to sell the 38 small cars, s₂  = 24 days

The 95% confidence interval is given as follows;

Using a graphing calculator, we get, the critical-t, [tex]t_c[/tex] = 2.055529

[tex]\left (\bar{x}_1-\bar{x}_{2} \right ) \pm t_{c} \cdot\sqrt{\dfrac{s _{1}^{2}}{n_{1}}+\dfrac{s _{2}^{2}}{n_{2}}}[/tex]

[tex]\left (95-48 \right ) \pm 2.055529 \times \sqrt{\dfrac{32^{2}}{18}+\dfrac{24^{2}}{38}}[/tex]

We get C.I. = 29.55259 < μ₁ - μ₂ < 64.44741

∴ C.I. ≈ 29.55 < μ₁ - μ₂ < 64.45

Answer:

Yes, it's true

Step-by-step explanation:

A fraction is a part of a whole number for example 1/2. 1/2 is a half of one whole piece and if you multiply it into any whole number whether it's 2,4,6,8,10...... basically, if you multiply a fraction less than one with a non-zero whole number, it will always be less than the whole number it's being cut into smaller pieces. However, if the fraction is greater than 1, we would technically have an answer greater than the whole number product, just something to remember.

Answer:

There is a 40% chance that she will choose a can of beef soup, a 20% chance that she will choose a can of chicken soup, and a combined 60% chance that she will choose a can of beef or chicken soup.

Step-by-step explanation:

Since Ms. Vellejo has 1 can of tomato soup, 4 cans of chicken soup, 3 cans of cheese soup and 2 cans of beef soup in her cabinet, and she will randomly choose one can of soup, to determine what is the probililty that she will choose a can of beef or chicken soup, the following calculation must be performed:

1 + 4 + 3 + 2 = 10

Beef soup = 2 cans = 2/10 = 0.2 = 20%

Chicken soup = 4 cans = 4/10 = 0.4 = 40%

20 + 40 = 60

Thus, there is a 40% chance that she will choose a can of beef soup, a 20% chance that she will choose a can of chicken soup, and a combined 60% chance that she will choose a can of beef or chicken soup.

Answer:

5 lbs

Step-by-step explanation:

90 - 53.10 = 36.90

She spent $36.90 on coffee. Since it cost $7.38 per pound, we can divide the total cost by 7.38 to figure out how many pounds she bought:

36.90 / 7.38 = 5

Raina bought 5 pounds of coffee.

Step-by-step explanation:

Answer:

Vertical/ x = 25.

Step-by-step explanation:

Vertical angles are self-explanatory; vertical angles are angles that are vertical from each other.

Vertical angles are also congruent (equal), meaning that both angles equal 75°.

4x - 25 = 75.

To solve this expression, we must first add 25 to 75. This is because there is a subtraction sign in front of 25, so we must do the opposite.

25 + 75 = 100

Lastly, divide 100 from 4.

4x = 100

100 / 4 = 25

x = 25

Answer:

Population after 16 year = 927 people (Approx.)

Step-by-step explanation:

Given:

Decrease rate = 10% per year

Current population = 5,000

Find:

Population after 16 year

Computation:

A = P[1-r]ⁿ

A = 5,000[1-0.1]¹⁶

A = 5,000[0.9]¹⁶

A = 5,000[0.1853]

A = 926.51

Population after 16 year = 927 people (Approx.)

Answer: False

Step-by-step explanation:

Events can be classed as being dependent or independent depending on whether the outcome of a certain event affects the outcome of another. In the scenario above, the success rate of jumps in the Northeast direction is higher than in the southwest direction and even much than in other directions. With these uneven rate of success, the probability that a fox will have a successful jump will depend on the direction in which the fox is jumping. With an high expected success probability in the Northeast and southwest than in other directions

Answer:

b = 5.7

A = 51.1°

B = 38.9°

Step-by-step explanation:

a = 7

c = 9

✔️Find b using Pythagorean theorem:

b = √(9² - 7²) ≈ 5.7

✔️Find A using trigonometric function:

Reference angle = A

Opposite = a = 7

Hypotenuse = c = 9

Apply SOH:

[tex] sin(A) = \frac{Opp}{Hyp} [/tex]

[tex] sin(A) = \frac{7}{9} [/tex]

[tex] A = sin^{-1}(\frac{7}{9}) [/tex]

A = 51.0575587° = 51.1°

✔️B = 180 - (90 + 51.1) (sum of triangles)

B = 38.9°
